Tablets, capsules, and liquid preparations such as syrups, elixirs, and simple solutions, with the usual pharmaceutical carriers are used for oral or sublingual administration. For rectal or vaginal administration, suppositories prepared as known in the art are used. For tissue implants, a sterile tablet or silicone rubber capsule or other object containing or impregnated with the substance is used. On certain occasions it may be advantageous to administer the compounds of this invention as clathrate compounds with substances such as α-cyclodextrin.

The prostaglandins are a family of closely related compounds which have been obtained from various animal tissues and which stimulate smooth muscle, lower arterial blood pressure, antagonize epinephrine-induced mobilization of free fatty acids, and have other pharmacological and autopharmacological effects in mammals. See Bergstom, et al., J. Biol. Chem., 238, 3555 (1963) and Horton, Experientia, 21, 113 (1965) and references cited therein. All of the so called natural prostaglandins are derivatives of prostanoic acid: ##STR97## The hydrogen atoms attached to C-8 and C-12 are in trans-configuration. The natural prostaglandins represent only one of the possible optical isomers. The compounds of this invention include all possible optical isomers and racemates.

The configuration of substituents on the prostaglandin molecule are designed to be in the α-configuration if they lie beneath the plane of the molecule as drawn above and are designed with a - - - - bond. Those substituents which lie above the plane of the molecule as drawn above are designated β and are represented by a bond.

The compounds of this invention which have the structure as shown in formula (A) wherein T, Z, R₃, Y, m, n, s and X are as herein above defined are said to be in the same configuration as the natural prostaglandins with respect to the configurations at C₈, C₁₁ and C₁₂ and are designated by the prefix nat. The enantiomer, represented by formula (B) is said to be in the mirror image or ent configuration. A substituent at C₁₁ drawn with a dotted line (C₁₁ - - - R₃) is said to have an α configuration; a solid line (C₁₁ --R₃) indicates a β configuration. The configuration at Y and X will be expressed in terms of R and S as is understood in the art. For example, the compound represented by formula (C) is named nat-15S,16S-11α,15-dihydroxy-1-(hydroxymethyl)-1,9-dioxo-15,-16-trimethylene-13-trans-prostene; its enantiomer (formula D) is named ent-15R,16R-11α,15-dihydroxy-1-(hydroxymethyl)-1,9-dioxo-15,16-trimethylene-13-rans-prostene. The racemate [ 1:1 mixture of (C) and (D)] is named nat-15S,16S-(and ent-15R,16R)11α,15-dihydroxy-1-(hydroxymethyl)-1,9-dioxo-15,16-trimethylene-13-trans-prostene. In a similar manner, the compounds represented by formulae (E) to (J) have the configurations shown below. ##STR98##

In each of the above formulae (C to J) the hydroxy group at C₁₁ is named "-11α-hydroxy".

The novel compounds of this invention can be prepared by a novel 1,4-conjugate-addition procedure involving treatment of the ether blocked cyclopentenone such as (129) or (111) with a lithio-cuprate reagent such as (117), (118), or (119) prepared as illustrated in Flowsheets A thru N.

The 1,4-conjugate-addition procedure is described hereinbelow in Flowsheet N. The preparation of the various requisite 1-iodo-trans-1-alkenyl or 1-tributylstannyl-trans-1-alkenyl derivative is illustrated in Flowsheets A-H and the novel and important methods of preparation of the 4-hydroxycyclopentenones embracing the 1-(hydroxymethyl)-1-oxo α chain is described in connection with Flowsheets I-M. ##STR99## wherein ' is one or two inclusive.

In accordance with the scheme as outlined hereinabove in Flowsheet A, carbethoxycyclobutane or carbethoxycyclopentane is converted to its enolate anion (2) by treatment with a strong base such as lithium cyclohexylisopropylamide, prepared from the corresponding amine and n-butyl lithium (hexane solution) in a solvent, such as anhydrous tetrahydrofuran, at very low temperatures, such as -78° C. The resulting enolate anion (2) is then alkylated with R₆ 3-X (3) to provide (4), the ester group of which is reduced to alcohol (5) by reaction with 2 equivalents of diisobutyl aluminum hydride, lithium aluminum hydride or the like. Oxidation of alcohol (5) with dipyridine chromium oxide complex ["Reagents for Organic Synthesis", L. F. Fieser and M. Fieser, John Wiley and Sons, Inc., New York, 4, 215 (1974;)], prepared in situ in methylene chloride solution, provides the corresponding aldehyde (6), which can also be obtained directly from ester (4) by partial reduction with one equivalent of diisobutyl aluminum hydride at -78° C., but the former two-step procedure is preferable. Reaction of aldehyde (6) with lithium acetylide ethylene diamine complex provides the 3-hydroxy-1-alkyne (7), which is converted to its trimethylsilyl ether in the usual manner. The silylated derivative is then treated with disiamylborane (prepared in situ in tetrahydrofuran solution at ice bath temperature from 2-methyl-2-butene, sodium borohydride and boron trifluoride ethereate) and then anhydrous trimethylamine oxide. The resulting solution and an iodine solution in tetrahydrofuran are then added simultaneously to an aqueous solution of sodium hydroxide to give the 1-iodo-3-trimethylsilyloxy-4,4-methylene-1-alkene (8). Also, the above sequences of reactions can be accomplished, as shown in Flowsheet A, using R₉ CH₂ X where R₉ is a phenyl group. ##STR100##

In accordance with the scheme as outlined hereinabove in Flowsheet B, 1-trimethylsilyl-3-tetrahydropyranyloxy-1-propyne (9) is treated with n-butyllithium at -78° C. and then with a freshly prepared solution of zinc iodide in anhydrous tetrahydrofuran, also at -78° C. Reaction of aldehyde (10) with the resulting reagent then provides the 4-hydroxy-3-tetrahydropyranyloxy-1-alkyne (11). This reaction procedes with great stereoselectivity and the product (11) is in the crythro configuration. [For additional information concerning this reaction see the examples which follow and F. Mercier, R. Epstein and S. Holland, Bull. Soc. Chim. France, 690(1972)].

The tetrahydropyranyl group in (11) is removed on weak acid treatment and the resulting crythro diol (12) can be reblocked by treating with an appropriate aldehyde or ketone ##STR101## in the presence of strong acid catalyst in the usual way to give the ketal or acetal (13). Acetone is a useful ketone for this purpose and the product (13) is then a 3,4-isopropylidenedioxy-1-alkyne. It is also possible to utilize silyl blocking groups (introduced after removal of the 1-trimethylsilyl group) to ultimately give the vinyl iodides (16) or (17). Weak base treatment of (13), for example heating for about one hour in refluxing methanol with potassium carbonate, results in desilylation to give (14). The 1-alkene (14) is converted to the corresponding 1-iodo-trans-1-alkene (15) by treatment with disiamylborane (prepared in situ in tetrahydrofuran solution at ice bath temperatures form 2-methyl-2-butene, sodium borohydride and boron trifluoride ethereate) and then anhydrous trimethylamine oxide. The resulting solution and an iodine solution in tetrahydrofuran are then added simultaneously to an aqueous solution of sodium hydroxide to give (15).

For the preparation of the threo derivatives, the 4-hydroxy-3-tetrahydropyranyloxy-1-alkyne (11) is acetylated to provide the corresponding 4-acetoxy derivative (18). The tetrahydropyranyl group is preferentially hydrolized with weak acid to (19), which is then tosylated in the usual manner to afford the erythro-3-tosyloxy-4-acetoxy-1-alkyne (20). Solvolysis of (20) under essentially neutral conditions by heating in aqueous tetrahydrofuran in the presence of an insoluble acid-acceptor, such as calcium carbonate, results in inversion of C₃, furnishing the threo-3-hydroxy-4-acetoxy-1-alkyne (21), which is then deblocked with aqueous base to give the threo-3,4-diol (22). Diol (22) is converted to an acetal or ketal (23) [or silyl derivatives as in (16) or (17)] and thence to the 1-iodo-trans-1-alkene (16) as described hereinabove wherein Ra is lower alkyl (C₁ or C₃).

For the preparation of the 16-alkoxyprostanoic acids of this invention, the erythro-4-hydroxy-3-tetrahydropyranyloxy-1-alkyne (11) is desilylated by methanol-potassium carbonate treatment and the resulting (25) is alkylated to give the 4-alkoxy-3-tetrahydropyranyloxy-1-alkyne (26). A useful procedure for this last step involves treatment of (25) with a molar equivalent of sodium hydride to give the 4-alkoxide which is then alkylated with the appropriate alkylating agent, for example methyl iodide. The 4-alkoxy-1-alkyne (26) is then converted to the corresponding 1-iodo-trans-1-alkene (27) as described hereinabove for the preparation of (15). If desired the tetrahydropyranyl blocking group in (27) can be hydrolyzed (weak acid) and the resulting free 3-ol corresponding to (27) converted to the 3-trimethylsilyloxy derivative (28), all in the usual manner wherein Ra is lower alkyl (C₁ to C₃).

For the threo series, the tetrahydropyranyl group in erythro-4-alkoxy-1-alkyne (26) is cleaved and the resulting 3-hydroxy-4-alkoxy-1-alkyne (29) is tosylated to give the erythro-3-tosyloxy-4-alkoxy-1-alkyne (30). Sn₂ displacement reaction with (30) with reagents such as tetrahydroammonium formate results in inversion to the threo derivative (31) saponification of which provides threo-3-hydroxy-4-alkoxy-1-alkyne (32). Trimethylsilylation followed by the vinyl iodide conversion procedure described hereinabove furnishes the threo-1-iodo-1-alkene (33) wherein Rd is hydrogen or lower alkyl (C₁ to C₃).

The 15-alkyl and/or 16-alkyl derivatives of this invention can be prepared by substituting ##STR102## for (9) and/or ##STR103## for (10) (R'₅ =lower alkyl of 1 to 3 carbons) in Flowsheet B.

In accordance with the procedure as outlined in Flowsheet C, an aldehyde (34) is treated with propargylic magnesium halide to form the homopropargylic alcohol (35), which is converted to its trimethylsilyl ether in the usual manner. The silylated derivative is then treated with disiamylborane (prepared in situ in tetrahydrofuran solution at ice bath temperature from 2-methyl-2-butene, sodium borohydride and boron trifluoride ethereate) and then anhydrous trimethylamine oxide. The resulting solution and an iodine solution in tetrahydrofuran are added simultaneously to a sodium hydroxide to give the 1-iodo-4-trimethylsilyloxy-trans-1-alkene (36), precursors for 16-hydroxy-prostaglandin.

The trimethylsilyl protecting group is removed with mild acid and the resulting vinyl iodide alcohol is oxidized with pyridinium chlorochromate to provide the 1-iodo-4-oxotrans-1-alkene (37), which upon treatment with a Grignard reagent (R₁₃ MgX) provides the 1-iodo-4-hydroxy-trans-1-alkene, which is silylated in the usual manner to provide the silyl ether (38) wherein R₁₁ ' is lower alkyl (C₃ to C₇) or lower alkenyl group (C₃ to C₅) and R₁₃ is vinyl, cyclopropyl or ethyl. ##STR104##

A more preferred method for the preparation of vinyllithium precursor is also described in Flowsheet C. Treatment of the requisite carboxylic acid (39a or 39) with the appropriate organolithium reagent (R₁₃ Li or R₁₁ ' Li respectively), wherein R₁₁ ' and R₁₃ are hereinabove defined, give the corresponding ketone (40) which upon treament with propargylic magnesium halide provides the homopropargylic alcohol (41) which is converted to the trans vinylstannyl derivative by sequential treatment with chlorotrimethylsilane and tri-n-butyltin hydride. Treatment of the vinylstannyl reagent (42) with n-butyllithium at a temperature of -10° C. to -78° C. generates the corresponding vinyllithium reagent. ##STR105##

In accordance with Flowsheet D hereinabove, the precursors for other 16-hydroxy prostaglandins are prepared by treating an appropriate aldehyde or ketone (43) with a propargylic magnesium halide to yield the requisite homopropargylic alcohol (44). The alcohol is protected as a tritylether (45) (second secondary alcohols) or as a trimethylsilyl ether (45) (for tertiary alcohols). These ethers are then converted to the appropriate trans-vinyliodide (46) by treatment with disiamylborane generated in situ from 2-methyl-2-butene, sodium borohydride, and boron trifluoride, followed by treatment with trimethylamine oxide and then iodine and sodium hydroxide, wherein R₁₅ is hydrogen, methyl or ethyl; Z is O-C(C₆ H₅)₃ when R₁₅ is hydrogen and Z is O-Si(CH₃)3 when R₁₅ is methyl or ethyl; R₁₄ is selected from the group comprising lower alkyl (C₃ or C₅), lower 1-alkenyl (C₃ to C₅), ##STR106## wherein R₇ is as described above with the proviso that when R₁₄ is ##STR107## then R₁₅ must be hydrogen. ##STR108##

The preparation of the precursors for the synthesis of 16-aryloxy congeners is described in accordance with Flowsheet E hereinabove. The aryl esters (49) are prepared by esterifying the commercially available acids or by treatment of ethyl bromoacetate with the appropriate phenol. The ester (49) is carefully reduced to the aldehyde (50) which upon treatment with lithium acetylide provides the propargylic alcohol (51). Treatment of the alcohol (51) with chlorotrimethylsilane followed by tri-n-butyltin hydride furnishes the requisite vinylstannyl derivative (53). Similar treatment starting with substituted hydrocinnamaldehyde (50a) provides the respective vinylstannyl derivative (53a).

The preparation of the precursors for the synthesis of secondary 15-hydroxy congeners are described in the literature. The preparation of the precursor for 15-methyl-15-hydroxy is described in Flowsheet F hereinbelow. In accordance with Flowsheet F, an acid chloride, wherein R₅ is hereinabove defined, is treated with acetylene and aluminum trichloride to provide the vinylchloride (55) which upon treatment with sodium iodide furnishes the vinyliodide (56). Treatment of (56) with methylmagnesium halide followed by chlorotrimethylsilane gives the requisite protected vinyliodide (57) ##STR109##

The precursors for the novel compounds of this invention which have a β chain represented by Formuler K ##STR110## wherein s, y, m, n, and X are herein above defined is shown in Flowsheet G and Flowsheet H. ##STR111##

In accordance with the scheme as outlined hereinabove in Flowsheet G a ketone (58) is reacted with a Grignard reagent (59) such as acetylene magnesium chloride (59, s=0) or propargyl magnesium bromide (59, s=1) to give the acetylenic alcohols (60). In those cases where X is not --CH₂ -- two isomeric acetylenic alcohols are formed. These isomers can be separated by procedures well known to the art including fractional crystallization, fractional distillation and various chromatographic procedures. The individual isomers can then be carried through the remaining reactions outlined in Flowsheet G.

The acetylenic alcohol (60) is converted to its trimethylsilyl ether in the usual manner. The silylated derivative (61) is then treated with diisomaylborane (prepared in situ in tetrahydrofuran solution at ice bath temperatures from 2-methyl-2-butene, sodium borohydride and boron trifluoride ethereate) and then anhydrous trimethylamine oxide. The resulting solution and an iodine solution in tetrahydrofuran are then added simultaneously to an aqueous solution of sodium hydroxide to give the 1-iodo-3-trimethylsilyloxy-trans-1-alkene (62).

(63) in turn is readily prepared by the addition of tri-n-butyl tin hydride to the acetylene (61) in the presence of bisazoisobutyronitrile followed by vacuum distillation at a high enough temperature (about 170° C.) to isomerize any of the cis-vinyl tin compound to the trans-vinyl tin compound.

Certain of the ketones (67) of this invention are prepared as indicated in Flowsheet H below: ##STR112## wherein n and m are as hereinabove defined and the moiety ##STR113## represents a phenoxy group which is optionally substituted with one or more halogen, trifluoromethyl, and lower alkoxy (C₁ to C₄) groups.

As indicated in Flowsheet H the reaction of an epoxide (64) with a substituted or unsubstituted phenol (65) in the presence of a catalytic amount of aqueous sodium hydroxide and a phase transfer catalyst such as methyl tricapryly ammonium chloride and the like at 70°-80° C. gives the phenoxy substituted alcohol (66) which in turn is oxidized with an oxidizing reagent such as pyridinium chlorochromate in methylene chloride to give the phenoxy substituted ketone (67) This ketone (67) is then carried through the reactions shown in Flowsheet G above.

The other ketones (58) used in this invention are known in the literature or can be made by procedures well known to the art [G. Lardelli, U. Lamberti, W. T. Walles and A. P. de Jonge, Rec. Trav. Chem. Pays-Bas, 86, 481 (1967); Ng. Ph. Buu-Hoi, T. B. Loc and Ng. Dat. Xuong., Bull. Soc. Chem. France, 174 (1958); and G. H. Fosner, Organic Reactions, 19, 1 (1972)].

The preparation of the cyclopentenones of this invention containing the hydroxyketone feature (68) wherein Z is hereinabove defined and R₃ ' is hydrogen or a hydroxy group can be accomplished in several ways one of which involves the conversion of the corresponding cyclopentenone containing a carboxylate function (69) to the respective hydroxyketone analog (68). ##STR114## Most of the cyclopentenone carboxylic acids (69) required for the purposes of this invention have been described in the literature or can be prepared by procedures quite analogous to those already described. Appropriate references are provided in the examples which follow. The synthesis of certain non-reference requisite cyclopentenone carboxylic acids (69) is also described herein.

The preparation of the requisite 4-hydroxy-thiacyclo pentneones (75) is described in Flowsheet I. In accordance with Flowsheet I which is hereinbelow described, treatment of 2-furyllithium (70) with a ω-chloroaldehyde (71) provides the chloroalcohol (72). Treatment of the chloroalcohol (72) with ethylmercaptoacetate furnishes the hydroxyester (73) which upon hydrolysis with sodium formate/formic acid provides the 3-hydroxy-cyclopentenone (74). Treatment of the cyclopentenone (74) with sulfuric acid provides the required 4-hydroxy-cyclopentenone (75). ##STR115##

The conversion of the cyclopentenone carboxylic acid (69) to the respective hydroxyketone analogs (68) and the protection of these compounds for a conjugate addition reaction is described hereinbelow in Flowsheets J and K.

For the preparation of cyclopentenones of the type (79) wherein Z is hereinabove defined, the carboxylic acid (76) is converted to the acid chloride (77) by first forming the sodium salt with sodium hydride in tetrahydrofuran (THF) and then reacting the resulting suspension with oxalyl chloride in the presence of a catalytic amount of dimethylformamide (DMF). The resulting acid chloride (77), dissolved in ether, is then added dropwise to an ether solution containing two to three equivalents of diazomethane to produce the diazoketone (78). The diazoketone can by hydrolized to the hydroxy ketone (79) by refluxing an etheral solution in the presence of a dilute aqueous solution of sulfuric acid.

Alternatively, the acid chloride (77) can be heated with two equivalents of 1,1,2-tris-trimethylsilyloxyethylene at 90°-100° for 2 to 4 hours to produce compound (81). Compound (81) can be readily hydrolized and decarboxylated to give the hydroxyketone (79) by treatment with dilute hydrochloric acid in tetrahydrofuran (THF).

Protection of the hydroxy ketone function of 79, suitable for a conjugate addition reaction, can be accomplished in two ways. Ketalization of 79 with ethylene glycol is accomplished by refluxing a benzene or toluene solution of 79 and ethylene glycol itno a Dean-Stark trap. The resulting ketal (82) is then treated with trimethylsilylchloride (TMSC1) and imidazole in dimethylformamide (DMF) to give 83 which is suitablely protected for a conjugate addition reaction.

Alternatively 79 can be protected by the reaction with a mixture of 2-methoxy-1-propene (84) and 2,2-dimethoxypropane (85) in benzene in the presence of an acid catalyst such as p-toluenesulfonic acid to give the ketal 86 which is suitablely protected for a conjugate addition reaction. ##STR116##

The preparation of the 4-hydroxycyclopentenones of this invention (92) wherein Z is hereinabove defined is outlined in Flowsheet K below. The reaction of the hydroxy acid (87) with at least two equivalents of dimethyl-t-butylsilychloride in the presence of imidazole in dimethylformamide at 30°-40° C. gives the bis-dimethyl-t-butylsilated compound 88. The carboxylate dimethyl-t-butylsilyl group can be selectively removed by treatment with acetic acid, tetrahydrofuran and water (4:2:1) to give the carboxylic acid (89). The acid chloride (90) is prepared by first treating the acid (89) with sodium hydride in tetrahydrofuran to give the sodium salt. The resulting suspension of the sodium salt is then treated with oxalyl chloride in the presence of a catalytic amount of dimethylformamide. Alternatively the acid chloride (90) can be prepared directly by the reaction of the acid (89) or the dimethyl-t-butylsilyl ester (88) with oxalyl chloride in tetrahydrofuran in the presence of a catalytic amount of dimethylformamide at 0° C. The slow addition of an etheral solution of the acid chloride (90) to an etheral solution of two to three equivalents of diazomethane gives the diazoketone (91) which on acid hydrolysis gives the 4-hydroxy cyclopentenone (92) containing the hydroxyketone function.

Alternatively the acid chloride (90) can be heated with at least two equivalents of 1,1,2-tris-trimethylsilylethylene at 90°-120° C. in the absence of a solvent to give compound (93) which is readily hydrolized and decarboxylated to give the 4-hydroxycyclopentenone (92) containing the hydroxyketone feature. Protecting of 92 can be accomplished by treatment with an excess of a mixture of 2-methoxy-propene (84) and 2,2-dimethoxypropane (85) in benzene with an acid catalyst such as p-toluenesulfonic acid to give the bis-ketal (94) which is suitably protected for a conjugate addition reaction. ##STR117##

Another preparation of the 4-hydroxycyclopentenones of this invention which contain a cis double bond in the potential α chain (109) is shown hereinbelow in Flowsheet L wherein g is as hereinabove defined. As illustrated in Flowsheet L there are three methods available to prepare the important intermediate 98. The reaction of the ω-bromo carboxylic acid (95) with oxalyl chloride in an inert solvent such as benzene gives the acid chloride (96). Addition of the acid chloride (96) in ether to an etheral solution of diazomethane (2 to 3 equivalents) yields the diazoketone (97) which can be hydrolyzed in a two phase system consisting of ether and dilute sulfuric acid to the hydroxyketone (98). Alternatively the acid chloride (96) can be treated with an excess of 1,1,2-tris-trimethylsilyloxyethylene in the presence of a catalytic amount of stannic chloride in the absence of solvent to give compound (99) which can readily be hydrolized and decarboxylated to the desired hydroxyketone (98) using dilute hydrochloric acid in tetrahydrofuran. An alternate method to prepare (98) involves the reaction of the bromo-olefin (100) with aqueous n-bromosuccinimide (NBS) in the presence of a catalytic amount of acetic acid to give a mixture of bromohydrins (101 and 102). Oxidation of the mixture of bromohydrins with an oxidizing agent such as pyridinium chlorochromate in methylene chloride gives a mixture of bromoketone (103) and bromoaldehyde (104). Refluxing this mixture with sodium formate in methanol then gives the desired intermediate (98). Protection of the ketone function of 98 is accomplished using ethylene glycol in refluxing toluene using a catalytic amount of p-toluenesulfonic acid. The ketal (103) is then reacted with dimethyl-t-butylsilylchloride and imidazole in dimethylformamide to give the fully protected compound 104. The phosphonium salt (105) is obtained by refluxing a solution of 104 and triphenylphosphine in acetonitrile. Treatment of the phosphonium salt (105) with sodium methylsulfinylmethide in dimethylsulfoxide generates a phosphonium yield which on reaction with aldehyde 106 gives 107. Refluxing a water-dioxane solution of 107 in the presence of a phosphate buffer (PH 5 to 6) gives the cyclopentenone (108). Treatment of 108 with chloral and triethylamine in ether gives (109) which on hydrolysis in a mixture of tetrahydrofuran and dilute hydrochloric acid at 50°-70° C. then gives the desired 4-hydroxycyclopentenone (110) which can be protected as described hereinabove in Flowsheet K.

Treatment of 109 with trimethylsilylchloride and imidazole in DMF gives 111 which is also suitably protected for a conjugate addition reaction. ##STR118##

The reagent 1,1,2-tris-trimethylsilyloxyethylene (80) and its use for the conversion of acid chlorides to hydroxyketone (for example 96 to 98 and 90 to 92) are claimed in this invention. The reagent preparation is described hereinbelow in Flowsheet M. The reaction of glycolic acid with 1,1,1,3,3,3-hexamethyldisilazane and trimethylsilylchloride in pyridine gives bis-trimethylsilated glycolic acid (113). Addition of (113) to a tetrahydrofuran solution of one equivalent of lithium 1,1,1,3,3,3-hexamethyldisilazane amide at -78° C. generates a lithium enolate which is trapped with trimethylsilylchloride to produce the desired reagent (80). ##STR119##

The preparation of the prostaglandin congeners of this invention are described hereinbelow in Flowsheet N where in Z is as hereinabove defined; R₃ " is hydrogen, 2-methoxypropyl-2-oxy (--OC(CH₃)₂ OCH₃) or trimethylsilyloxy; R₃ "' is hydrogen or hydroxy; T' is the radical ##STR120## wherein R₁ is as hereinabove defined. R' is selected from the group consisting of: ##STR121## wherein R₅, R₆, R₇, R₈, R₉, R₁₀, R₁₁, R₁₃, G, p, q, t, s, m, n, y, and X are as hereinabove defined.

In accordance with Flowsheet N the vinyliodide (114) is treated with either one equivalent of n-butyllithium or 2 equivalent of t-butyllithium at low temperature, preferably -30° to -70° C. in an inert solvent, eg. hexane, ether or toluene to provide the trans alkenyl-lithium reagent (116).

Alternatively, the vinyllithium reagent (116) can be prepared by treatment of a vinylstannyl derivative such as (115) with n-butyllithium at -10° to -78° C. in ether or THF.

For the preparation of the asymmetrical lithio cuprate (117) or the like, a solution of one molar equivalent of copper (I)-1-alkyne, preferably copper (I)-1-pentyne in anhydrous hexamethylphosphorous triamide preferably one to five molar equivalents, and anhydrous ether is added to one molar equivalent of the aforementioned vinyllithium solution cooled to about -78° C. After about one hour at this temperature, a molar equivalent of the requisite cyclopentenone (120) is added. After several hours at -78° C. to -20° C. the reaction mixture is quenched with aqueous ammonium chloride solution and the blocked product (121) is isolated in the usual manner.

It is also possible to effect conjugate 1,4-addition with the asymmetrical lithio cuprate (119) derived from vinyllithium (116) and cuprous thiophenoxide. A solution of vinyllithium (116) in ether at -78° C. is reacted with an equimolar amount of a reagent prepared by admixture, in ether at a temperature of 0° C. to -78° C., of equimolar amounts of cuprous thiophenoxide and copper (I) iodide tributylphosphonium complex. After about 30 minutes at this temperature, the lithio cuprate (119) is treated with the requisite cyclopentenone (120) as described hereinabove for the conjugate addition with 1-alkynyl lithio cuprate (117).

For the preparation of the symmetrical lithio cuprate (118) one molar equivalent of copper (I) iodide tributylphosphine complex, dissolved in anhydrous ether, is added at about -78° C. to two molar equivalents of the aforementioned vinyl lithium (116) solution in hexanes, cooled to -78° C. After about one hour at this temperature, the lithio cuprate (118) is treated with the requisite cyclopentenone (120) as describe hereinabove for the conjugate addition with the 1-alkynyl lithio cuprate (117).

The procedures for conjugate addition involving organocopper reagents are well known in the art, see for example, C. J. Sih, et al., J. A. C. S., 97, 865 (1975).

All available evidence leads us to believe tha the --CH═CH--R'₂ function introduced by the cuprate process occupies a position trans to the 11-oxy function. Similarly, we are led to the conclusion that in the product (121) the two side-chains attached to C₈ and C₁₂ are trans to each other. However, we are not certain of this configurational relationship in the product as it is obtained directly from the cuprate process. These products may have the side-chains in a trans- or cis-relationship or they may be a mixture containing both the trans- and cis-isomers. This is indicated in the nomenclature of the compounds involved by the designation 8ε. In order to ensure a trans-relationship in (121) these products can be submitted to conditions known in the literature to equilibrate the cis-8-iso-PGE₁ to a mixture containing about 90% of the trans product. These conditions involve treatment with potassium acetate in aqueous methanol for 96 hours at room temperature. ##STR122##

When T' is ##STR123## removal of the blocking groups from (121) to give the prostaglandin congener (122) is accomplished by treatment of (121) with a mixture of acetic acid, tetrahydrofuran and water (4:2:1) at 25° to 55° C.

When T' is ##STR124## (121) can be partially deblocked to give the ketal (123) by treatment of (121) with 0.6 N hydrochloric acid in tetrahydrofuran at room temperature for 4 to 7 hours.

In certain cases it is possible to convert the carboxylic acid function of a prostaglandin congener into a terminal hydroxymethyl ketone function as shown in Flowsheet O hereinbelow wherein Z, C₁₃ -C₁₄, and R is as hereinabove defined. Treatment of a prostaglandin congener (124) in which the hydroxy groups of the β chain are protected with a suitable group such as acetate or a dimethyl-t-butylsilyl ether with oxalyl chloride in benzene for 2 to 5 hours furnishes the acid chloride (125). Addition of the acid chloride (125), dissolved in ether, to an ether solution of at least three equivalents of diazomethane gives the diazoketone (126). Hydrolysis of the diazoketone using aqueous sulfuric acid and tetrahydrofuran at 55° C. gives the hydroxymethyl ketone analog (127). The acetate protecting group can be removed by refluxing with acidified methanol. The dimethyl-t-butylsilyl ether protecting group can be removed by treatment with aqueous hydrochloric acid in tetrahydrofuran at 25° to 60° C. ##STR125##

When the compounds of this invention are prepared from racemic starting compounds two racemates are obtained. In appropriate instances these racemates can be separated from each other by careful application of the usual chromatographic procedures. In the more difficult instances it may be necessary to apply high pressure liquid chromatography including recycling techniques. [See G. Fallick, American Laboratory, 19-27 (August, 1973) as well as references cited therein. Additional information concerning high speed liquid chromatography and the instruments necessary for its application is available from Waters Associate, Inc., Maple Street, Milford, Mass.].

It is also possible to prepare the compounds of this invention in their optically active forms by the conversion of the optically active 4-hydroxycyclopent-2-en-1-one carboxylic acids (128) to the optically active protected hydroxy ketone analog (129) using the methods outlined hereinabove in Flowsheet K. ##STR126##

Conjugate addition of the vinyl cuprates to (129) followed by deblocking as described hereinabove in Flowsheet N then gives the compounds of this invention in their optically active forms. Although in some cases two diasteroeisomers will be formed, each optically active, they can be separated by chromatographic procedures as described hereinabove.

The preparation of optically active 4-hydroxycyclopent-2-en-1-ones such as (128) is described hereinbelow.

The 4-hydroxycyclopentenone racemates may be resolved into their component enantiomers (130) and (131) by derivatizing the ketone function with a reagent having an optically active center. The resulting diasteromeric mixture can then be separated by fractional crystallization, or by chromatography, or by high speed liquid chromatography involving, if necessary, recycling techniques. Among the useful optically active ketone derivatizing reagents are 1-α-aminoxy-γ-methylpentanoic acid hydrochloride [to give (132), (R)-2-aminoxy-3,3-dimethylbutyric acid hydrochloride, and 4-α-methylbenzyl semicarbazide. After separation of the diasteromeric derivatives, reconstitution of the keto function provides the individual 4-hydroxycyclopentenone enantiomers (130) and (131). A useful procedure for the resolution of a 4-hydroxycyclopentenone racemate via an oxime such as (132) is described in the art [R. Pappo, P. Collins and C. Jung, Tetrahedron Letters, 943 (1973)]. ##STR127##

An alternate procedure for the preparation of the 4(R)-hydroxycyclopentenone enantiomers such as (130) involves as a key step the selective microbiological or chemical reduction of trione (133) to the 4(R)-hydroxycyclopentanedione (134). A wide variety of microorganisms are capable of accomplishing this asymmetric reduction, one of the most useful being Dipodascus unincleatus. This step also can be achieved chemically by catalytic hydrogenation in the usual manner (for example, under about one atmosphere of hydrogen in methanol) using a soluble rhodium catalyst with chiral phosphine ligands, such as (1,5-cyclooctadiene)-bis-(o-anisylcyclohexylmethylphosphine)rhodium (I) tetrafluoroborate in the presence of one equivalent of organic base, such as triethylamine.

Conversion of hydroxycyclopentanedione (134) to an enol ether or enol ester, (135, E=alkyl, preferably iso-propyl; aroyl such as benzoyl; or arylsulfonyl such as 2-mesitylenesulfonyl), is accomplished by treatment, for example, with isopropyl iodide and a base such as potassium carbonate in refluxing acetone for from 15 to 20 hours, or with a base such as triethylamine and 0.95 equivalents of benzoyl chloride or a slight excess of 2-mesitylenesulfonyl chloride, in a non-prototropic solvent at a temperature of about -10° to -15° C. Reduction of (135) with excess sodium bis(2-methoxyethoxy)aluminum hydride in a solvent such as tetrahydrofuran or toluene at low temperatures, such as -60° to -78° C., followed by mild acid hydrolysis (representative conditions: aqueous dilute hydrochloric acid, pH 2.5; or oxalic acid, sodium oxalate in chloroform) at ambient temperatures from 1 to 3 hours provides the 4(R)-hydroxycyclopentenone ester (136). The ester (136), can then be hydrolized to acid (130).

For a description of these procedures in the art see: C. J. Sih, et al, J. A. C. S., 95, 1776 (1973); J. B. Heather, et al., Tetrahedron Letters, 2213 (1973); R. Pappo and P. W. Collins, Tetrahedron Letters, 2627 (1972); and R. Pappo P. Collins, and C. Jung, Ann. N. Y. Acad. Sci., 180, 64 (1971). ##STR128##

Procedures for the preparation of the requisite cyclopentanetriones (133) are well-established in the art and generally involve the treatment of an ω-1-oxo long chain ester (137) with methyl or ethyl oxalate and a base such as sodium methoxide in methanol, followed by treatment with dilute hydrochloric acid in aqueous methanol to effect the dealkoxalylation of the intermediate (138). See J. Kutsube and M. Matsui, Agr. Bio. Chem., 33 1078 (1969); P. Collins, C. J. Jung and R. Pappo, Israel Journal of Chemistry, 6, 839 (1968); R. Pappo, P. Collins and C. Jung, Ann. N. Y. Acad. Sci., 180, 64 (1971); C. J. Sih, et al., J. A. C. S., 95, 1676 (1973) (see reference 7); and J. B. Heather, et al., Tetrahedron Letters, 2313 (1973) for pertinent background literature. ##STR129##

The intermediate keto esters (137) may be prepared by a variety of methods known to the art. One useful procedure is outlined below and involves alkylation of ethyl acetoacetate sodium salt (139) in the usual manner with the appropriate side-chain precursor (140, X═Cl, Br, I, preferably Br or I) followed by decarbethoxylation and reesterification, all in the usual manner. ##STR130##

The side-chain precursors (140) are commercially available where Z is --(CH₂)_(p) --, and can be prepared as described in Belgian Pat. No. 786,215 (granted and opened to inspection Jan. 15, 1973).

Those precursors wherein Z is --(CH₂)_(t) --O-CH₂ -- can be prepared by the transformation shown directly below starting with the mono-tetrahydropyranyl derivative (143). Thus, (143) is converted to the lithium alcoholate by treatment with butyl lithium, the alcoholate is then O-alkylated with ethyl) bromoacetate to provide (144), which on de-O-tetrahydropyranylation, mesylation and reaction with lithium bromide gives the required (145). (These and all the above-described transformations can be effected in the usual manner well-established in the art; pertinent examples for most of the reactions can be found in the above-cited Belgian Pat. No. 786,215.) ##STR131##

It is also possible to resolve the 4-hydroxycyclopentenone racemate (146) by microbiological means. Thus, treatment of the 4-O-alkanoyl or aroyl derivatives (147, R₁₈ =aryl or alkyl) of racemate (146) (preferably the 4-O-acetyl and 4-O-propionyl derivatives) with an appropriate microorganism, preferably a Saccharomyces species e.g., 1375-143, affords preferential de-O-acylation of the 4(R)-enantiomer to give (148), which is then separated from the unreacted 4(S)-O-acyl enantiomer (149) by chromatographic procedures. After separation, mild hydrolysis of the 4(S) derivative (149) provides the 4(S)-hydroxycyclopentenone (150). [See N.J. Marsheck and M. Miyano, Biochima et Biphysica Acta, 316, 363 (1973) for related examples.] ##STR132##

It is also possible to prepare the individual 4-hydroxycyclopentenones (148) and (150) directly by selective microbial hydroxylations of the corresponding 4-unsubstituted cyclopentenone (151). For example, with Aspergillus niger ATCC 9142; a selective 4(R)-hydroxylation of [151, Z=(CH₂)₆ ] has been reported; see S. Kurozumi, T. Tora and S. Ishimoto, Tetrahedron Letters, 4959 (1973). Other microorganisms can also accomplish this hydroxylation. ##STR133##

The 9 α-hydroxy compounds of this invention (154) are prepared by a conjugate addition reaction as described hereinabove in Flowsheet N. The initial conjugate addition product 121 (wherein Z, T', R"₃ and R are as hereinabove defined) is not deblocked but dissolved in tetrahydrofuran. An excess of lithium perhydro-9b-borophenalyhydride (PBPH) in tetrahydrofuran is added at -78° C. After warming to 0° C., the reaction mixture is quenched with saturated ammonium chloride solution. The product 153 is isolated and deblocked with acetic acid-tetrahydrofuran-water 4:2:1 at 40° C. in the cases where T' is ##STR134## and with dilute hydrochloric acid in the cases where T' is ##STR135## to give the 9α-hydroxy compounds of this invention (154). See Flowsheet P hereinbelow wherein Z, T', R"₃, R, R' and R"₃ are as hereinabove defined. ##STR136##

The 9β-hydroxy compounds of this invention (156) are prepared by preforming a conjugate addition as described hereinabove in Flowsheet N. The initial conjugate addition product 121 (wherein Z, T', R"₃ and R' are as hereinabove defined) is not deblocked but dissolved in ethanol and an excess of sodium borohydride is added. The mixture is stirred for 8 hours, poured into water and the reduced products 153 and 155 are obtained. These are deblocked with acetic acid-tetrahydrofuran-water 4:2:1 at 40° C. in the cases where T' is ##STR137## and with dilute hydrochloric acid in tetrahydrofuran in cases where T' is ##STR138## to give the 9α-hydroxy (154) and 9β-hydroxy (156) compounds of this invention which can be separated by silica gel chromatography. See Flowsheet Q hereinbelow wherein Z, T', R, R', R"₃, and R"'₃ are as defined hereinabove. ##STR139##

The 1-hydroxymethyl group of the compounds of this invention can be selectively esterified by dissolving the compound (154 or 156) in pyridine and adding one equivalent of an anhydride (R₁ CO)₂ 0 and allowing the mixture to stand overnight to give the desired esters (157 and 158). ##STR140##

The novel compounds of the present invention have potential utility as hypotensive agents, anti-ulcer agents, agents for the treatment of gastric hypersecretion and gastric erosion, agents to provide protection against the ulcerogenic and other gastric difficulties associated with the use of various non-steroidal antiinflammatory agents (e.g., indomethacin, aspirin, and phenylbutazone), bronchodilators, anti-inflammatory agents, abortifacients, agents for the induction of labor, agents for the induction of menses, fertility-controlling agents, oestrus regulators for use in animal husbandry with cattle and other domestic animals and central nervous system regulatory agents. Certain of the novel compounds of this invention possess utility as intermediates for the preparation of other of the novel compounds of this invention.

The novel compounds of this invention possess the pharmacological activity described below as associated with the appropriate above-described prostaglandin type.

The known PGE, PGFα, PGFβ, PGA and PGD compounds are all potent in causing multiple biological responses even at low doses. For example, PGE₁ and PGE₂ are extremely potent in causing vasodepression and smooth muscle stimulation, and also are potent as antilipolytic agents. Moreover, for many application, these known prostaglandins have an inconveniently short duration of biological activity. In striking contrast, the novel prostaglandin analogs of this invention are substantially more specific with regard to potency in causing prostaglandin-like biological responses, and/or having a substantially, longer duration of biological activity. Therefore, each of these novel prostaglandin analogs is suprisingly and unexpectedly more useful than one of the corresponding above-mentioned known prostaglandins for at least one of the pharmacological purposes indicated below for the latter, either because it has a different and narrower spectrum of biological activity than the known prostaglandins, and therefore is more specific in its activity and causes smaller and fewer undesired side effects than the known prostaglandins, or because of its prolonged activity, fewer and smaller doses of the novel prostaglandin analog can frequently be used to attain the desired result.

Another advantage of the novel compounds of this invention, compared with the known prostaglandins, is that these novel compounds are administered effectively, orally, sublingually, intraveginally, buccally, or rectally, in addition to the usual intravenous, intramuscular, or subcutaneous injection or infusion methods indicated above for the uses of the known prostaglandins. These qualities are advantageous because they facilitate maintaining uniform levels of these compounds in the body with fewer, shorter, or smaller doses, and make possible self-administration by the patient.

PGFα, and PGFβ, compounds, and their esters and pharmacologically acceptable salts, are extremely potent in causing various biological responses. For that reason, these compounds are useful for pharmacological purposes. See, for example, Bergstron, et al., Pharmacol. Rev. 20, 1 (1968), and references cited therein. A few of those biological responses are systemic arterial blood pressure lowering in the case of the PGE compounds as measured, for example, in anesthetized (phenobarbital sodium) pentolinium-treated rats with indwelling aortic and right hear cannulas; pressor activity, similarly measured, for the PGF compounds; stimulation of both muscle as shown, for example, by tests on strips of guinea pig ileum, rabbit duodenum, or gerbil colon; potentiation of other smooth muscle stimulants; antilipolytic activity as shown by antagonism of epinephrine-induced mobilization of free fatty acids or inhibition of the spontaneous release of glycerol from isolated rat fat pads.

Because of these biological responses, these known prostaglandins are useful to study, prevent, control, or alleviate a wide variety of disease and undesirable physiological conditions in birds and mammals, including humans, useful domestic animals, pets, and zoological specimens, and in laboratory animals, for example, mice, rats, rabbits, and monkeys.

For example, these compounds, are useful in mammals, including man, as nasal decogestants. For this purpose, the compounds are used in a dose range of about 10 mg to about 10 mg. per ml. of a pharmacologically suitable liquid vehicle or as an aersol spray, both for topical application.

The PGEβ compounds are useful as hypotensive agents to reduce blood pressure in mammals including man. For this purpose, the compounds are administered by intravenous infusion at the rate of about 0.01 mg. to about 40 mg per kg. of body weight per minute, or in a single or multiple doses of about 25 mg. to 2500 mg. per kg of body weight total per day.

The PGFα and PGFβ compounds are useful in place of oxytocin to induce labor in pregnant female animals, including man, cows, sheep, pigs, at or near terms or in pregnant animals with intrauterine death of the fetus from about 20 weeks to term. For this purpose, the compound is infused intraveneously at a dose of 0.01 mg to 50 mg. per kg. of body weight per minute until or near the termination of the second stage of labor, i.e., expulsion of the fetus. These compounds are especially useful when the female is one or more weeks postmature and natural labor has not started, or 12 to 60 hours after the membranes have ruptured and natural labor has not yet started.

The PGFα and PGFβ compounds are useful for controlling the reproductive cycle in ovulating female mammals, including humans and other animals. For that purpose, PFG₂α, for example, is administered systemically at a dose level in the range of 0.01 mg to about 20 mg. per kg. of body weight, advantageously during a span of time starting approximately at the time of ovulation and ending approximately at the time of menses or just prior to menses. Additionally, expulsion of an embryo or fetus is accomplished by similar administration of the compound during the first third or the second third of the normal mammalian gestation period. Accordingly, they are useful as abortifacients. They are also useful for induction of menses during approximately the first two weeks of a missed menstrual period and accordingly, are useful as contraceptive anti-fertility agents.

The novel compounds of this invention induce the biological responses described hereinabove as associated with its particular prostaglandin type. These novel compounds are accordingly used for the above-described corresponding purposes.

The novel PGFβ compounds of this invention are also useful as bronchodilators for the treatment of asthma and chronic bronchitis. As such, they may be conveniently administered by inhalation of aerosol sprays prepared in a dose range of about 10 mg. to about 10 mg./ml. of a pharmacologically suitable liquid vehicle. Relative to the natural prostaglandins, the PGE compounds in particular have the significant advantage of inducing prolonged effects.

The invention will be described in greater detail in conjunction with the following specific examples.

Chromatography on 135 g of florisil and eluting with 500 ml of hexanes furnishes 24 g of oily product which is shown to be contaminated with startin material and iodoform by infrared and thin layer chromatography. The material is purified by removing the trimethylsilyl group in the following manner. The crude product is dissolved in 350 ml of acetic acid-tetrahydrofuran-water (4:2:1) by stirring at ambient temperature for 5 minutes. The solvent is removed under reduced pressure and the residual oil containing mainly 1-iodo-3-hydroxy-4,4-trimethylene-1-trans-octen is applied to a 2" (flat) dry column containing 1200 g of Woelm silica gel. The column is developed with benzene, cut into one-inch segments and each segment is eluted with chloroform. Combination of the appropriate fractions affords 300 mg of iodomethane, 2.8 g of 4,4-trimethylene-1-octyne-3-ol, and 11.6 g of 1-iodo-3-hydroxy-4,4-trimethylene-1-trans-octene. Silylation of this material in the manner described above followed by distillation of the residual oil furnishes 13 g of pure product; bp 82°-84° C. (0.2 mm).

EXAMPLE 93 Preparation of 1-octyn-4-ol

A suspension of 24.3 g (1.0 mole) of magnesium in 90 ml of dry ether is stirred at room temperature under nitrogen with 100 mg of mercuric chloride. The reaction is initiated by the addition of 2 ml of propargyl bromide and maintained by the dropwise addition of a solution of 119.5 g (1.0 mole) of propargyl bromide and 107.7 g (1.25 mole) of valenaldehyde in 300 ml of dry ether. While the initial reaction is quite vigorous and is maintained at 30° C. only by cooling in an ice bath it may become necessary to heat the mixture to reflux temperature after about a third of the ether solution is added in order to maintain the reaction. After the addition is complete the reaction mixture is refluxed until most of the magnesium is dissolved (several hours) and the reaction mixture is decanted from excess magnesium into 1500 ml of stirred ice-cold ammonium chloride solution. The ether layer is separated and the aqueous layer is extracted three times with 300 ml portions of ether. The combined ether extract is washed with saturated sodium chloride solution, dried over magnesium sulfate and filtered. Evaporation of the ether under vacuum leaves about 115 g of yellow oil, which is distilled through a 15 cm Vigreaux column at 18 mm. The fraction boiling at 81°-82° C. is collected (36 g) and the higher-boiling and lower-boiling distillates may be redistilled to yield additional product. The infrared absorption spectrum shows at most a trace of allene (5.1μ) and gas-liquid partition chromatography shows a purity of about 98% for the main fraction.

EXAMPLE 107 Preparation of 1-iodo-4-triphenylmethoxy-trans-1-octene

To a stirred suspension of 1.78 g (0.074 mole) of sodium borohydride in 200 ml of dry glyme at -5° C. under nitrogen is added 15.8 g (0.22 mole) of 2-methyl-2-butene and 16.2 g (0.11 mole) of boron trifluoride etherate, and the mixture is stirred for 2 hours at -5° C. to 0° C. A solution of 37.5 g (0.10 mole) of 4-trityloxy-1-octyne (Example 98) in 50 ml of glyme is added to the cold solution during 5-10 minutes, and the solution is allowed to warm to 20° C. during 1.5 hours. The reaction mixture is cooled to 0° C. and 30 g (0.4 mole) of dry trimethylamine-N-oxide is added during 5 minutes. On removing the cooling bath the temperature rises to 40° C. and the mixture is kept between 30°-40° C. for 1.5 hours. The suspension is poured rapidly into one liter of ice cold 15% sodium hydroxide solution during good stirring and a solution of 80 g of iodine in 200 ml of tetrahydrofuran is added immediately. Stirring is continued for 30 minutes without further cooling and the organic layer is separated. The aqueous layer is extracted with three 200 ml protions of ether and the combined organic layers are washed successively with water, 5% sodium thiosulfate solution and saturated sodium chloride, dried over magnesium sulfate, filtered and evaporated to yield 50 g of yellow oil. The bulk of the oil is dissolved in hexane and, after decantation from a gummy solid the hexane solution is percolated through a 5.1 cm diameter column of 1500 g of alumina with additional hexane. Fractions containing the desired product are concentrated to a pale yellow oil (33 g) which has n.m.r. and infrared spectra characteristics of the desired product.

EXAMPLE 141 Stereoselective Hydrolysis of Racemic 4-benzoyloxy-1-octyne by Rhizopus arrhizus

An agar slant of R. arrhizus (MUMF 1638) is used to inoculate 7 shake flasks (250 ml Erlenmeyer). Each flask contains 50 ml of a medium consisting of 2% Edamine, 2% glucose, and 0.72% corn steep liquor in water with pH adjusted to 7.0. A total of 14 such flasks are incubated on a rotary shaker at 28° C. After 72 hours incubation, 50 mg of racemic 4-benzoyloxy-1-octyne (Example 135) in 0.1 ml of acetone is added to each flask. After 28 hours the flasks are harvested and worked up by extraction of the whole mash with an equal volume of chloroform. The combined extracts are dried over magnesium sulfate and concentrated. The resulting oil is chromatographed on a column of silica gel with hexane progressively enriched in ethyl acetate.

From fractions 3-6 is obtained 150 mg of colorless oil, identical to 4-benzoyloxy-1-octyne, [α]_(D) ²⁵ =5±1.0° (C=0.91, ethyl acetate). This compound has the (S)-configuration.

From fractions 13-20 is obtained 75 mg of colorless oil, identical to 4-hydroxy-1-octyne, [α]_(D) ²⁵ =-17±1.0° (C=0.77, ethyl acetate). This compound has the (R)-configuration.

The strain of R. arrhizus utilized in this experiment is a higher fungus which grows steadily on a variety of artificial media at 20°-25° C. In this study of the taxonomic aspects of the culture, Petri dishes of potato-dextrose, malt extract, and cornmeal agars were inoculated and incubated at ambient room temperature for 10 days. Observations of cultural and morphological characteristics are recorded in the description below:

Colonies on Petri dishes of potato-dextrose agar growing rapidly, covering the agar surface in 3-5 days and producing a thick, loose mat of grayish mycelium. Colony surface characterized by abundant black sporangia. Colony reverse grayish white. Colonies on malt extract agar growing rapidly, covering the agar surface in 3-5 days. Mycelial mat thick, grayish-yellow. Colony surface becoming brownish-black from masses of sporangia. Colony reverse yellowish. Colonies on cornmeal agar very thin, whitish; spreading across agar surface. Cultures transparent with relatively few sporangia porduced. Visibility of micromorphology is good on this mediu. Rhizoids produced sparingly along stoloniferous hyphae. Generally two to three sporangiophores arose from rhizoids. Walls of sporangiophores olive brown, 14.0-20.0 μm in width at base, tapering slightly to apex; 0.5-1.5 mm in length Sporangiophores terminated by spherical sporangia, 130-225 μm in diameter. Columellae hemispherical, 3-50 μm high by 50-70 μm wide. Spores brownish when mature, 6.0-8.5 μm×4.5-6.0 μm. Spore walls conspicuously marked by longitudinal striations.

The bulk of the methanol is evaporated at room temperature, and the mixture is extracted with ether. The extract is washed with brine, dried over magnesium sulfate, and evaporated to give a colorless oil, identical to 4-hydroxy-1-octyne [α]_(D) ²⁵ =+17±1.0° (C=0.77, ethyl acetate). This compound has the (S)-configuration.

EXAMPLE 211 Preparation of trans-1-Hydroxy-2-(3-trifluoromethyl)phenoxycyclopentane

A mixture of 88 g of cyclopentene oxide, 150.7 g of 3-trifluoromethylphenol, 5.0 g of sodium hydroxide in 30 ml of water and 4.0 g of methyltricaprylyl ammonium chloride is stirred at 70°-80° C. for 51 hours and at 25° C. for 96 hours. The mixture is then diluted with methylene chloride and poured into water. The organic layer is washed with dilute sodium hydroxide solution and water. The solution is dried over magnesium sulfate. The solvent is removed giving 221.5 g of a liquid which is distilled (bp 110°-113° C. 0.8 mm) giving trans-1-hydroxy-2-(3-trifluoromethyl)phenoxycyclopentane.

EXAMPLE 212

In the manner described above in Example 211 from 4-fluorophenol and cyclopentane epoxide is prepared trans-1-hydroxy-2-(4-fluoro)phenoxycyclopentane.

EXAMPLE 213

In the manner described above in Example 211 from 3-chlorophenol and cyclopentane epoxide is prepared trans-1-hydroxy-2-(3-chloro)phenoxycyclopentane.

EXAMPLE 214 Preparation of 2-(3-Trifluoromethylphenoxy)cyclopentanone

To a suspension of 327.43 g of pyridinium chlorochromate in one liter of methylene chloride is added 220 g of trans-1-hydroxy-2-(3-trifluoromethylphenoxy)cyclopentane in 500 ml of methylene chloride. The mixture is stirred for 2 hours 15 minutes. Another 50 g of the oxidizing agent is added and the mixing is stirred for 41/2 hours. The mixture is diluted with ether and decanted from a black residue which is washed with more ether. The combined solutions are filtered through silica gel. The solvent is removed. The residue is dissolved in ether and again filtered through silica-gel. The solvent is removed and the residue is distilled (bp 113°-116° C., 1.5 mm) to give 188 g of 2-(3-trifluoromethylphenoxy)cyclopentanone.

EXAMPLE 215

In the manner described above for Example 214 is prepared from the product of Example 212; 2-(4-(fluorophenoxy)cyclopentanone.

EXAMPLE 216

In the manner described above for Example 214 is prepared from the product of Example 213; 2-(3-chlorophenoxy)cyclopentanone.

EXAMPLE 217 Preparation of 1R,2S(and 1S,2R)-1-Ethynyl-1-hydroxy-2-butylcyclopentane and 1R,2R(and 1S,2S)-1-ethynyl-1-hydroxy-2-butylcyclopentane

Into 150 ml of dry tetrahydrofuran is bubbled purified acetylene, as a solution of 2.4 M n-butyl magnesium chloride (92 ml) is added dropwise with stirring over a 2 hour period. To the resulting solution of acetylene magnesium chloride is added 21 g of 2-butylcyclopentanone in 50 ml of tetrahydrofuran dropwise over 15 minutes. The solution is stirred for 30 minutes and then is poured into an ice cold solution of saturated ammonium chloride. The mixture is acidified to pH 5 and extracted with ether. The ether solution is washed with brine and dried over magnesium chloride. the ether is removed and the residue is distilled giving 14.8 g of a colorless liquid. This is chromatographed on a dry column of silica-gel eluting with benzene-ethyl acetate (19:1) to separate isomers giving 1R,2S(and 1S,2R)-1-ethynyl-1-hydroxy-2-butylcyclopentane and 1R,2R(and 1S,2S)-1-ethynyl-1-hydroxy-2-butylcyclopentane.

EXAMPLE 218 Preparation of 1-propargyl-1-hydroxycyclohexane

A stirred suspension of 121.6 g (5.0 mol) of magnesium in 1-1 of anhydrous ether is treated with 0.6 g of mercuric chloride and about 100 mg of iodine. After several minutes, 3 ml of propargyl bromide is added and if no exotherm is noted, a small amount of reacting propargyl bromide and magnesium in ether is added. When the reaction begins, a mixture of 5.0 mol of cyclohexanone and 595 g (5.0 mol) of propargyl bromide is added dropwise at a rate that produces vigorous refluxing of the solution. (The propargyl bromide must always be present in some excess otherwise the reaction will stop. If this happens, the addition of about 1 ml of propargyl bromide will restart the reaction.) After about half of the propargyl bromide-cyclohexanone mixture has been added, another 500-750 ml of ether is used to dilute the reaction mixture. At the end of the addition, the reaction mixture is refluxed for at least 0.5 hour, cooled and poured into 4 liters of saturated ammonium chloride during good stirring. The ethereal layer is separated and the aqueous layer is washed with ether several times and the combined extract is washed twice with saturated sodium chloride solution and dried over anhydrous magnesium sulfate. Evaporation of the ether yields 583 g (630 g theory) of a dark oil which is distilled giving purified 1-propargyl-1-hydroxycyclohexane.

EXAMPLES 423-445

By the methods described hereinabove in Examples 319 and 320, the 1,9-dioxo-1-hydroxymethyl prostene derivative shown in Table 33 are prepared by the indicated method from the indicated vinyl iodide or vinyl tin compound and the indicated cyclopent-2-en-1-one.

In those cases where two diastereoisomers are formed in the conjugate-addition, only one of the diastereoisomers is listed in Table 33. It should be understood that the other diastereoisomer is also formed which in its nat and ent forms has an opposite (mirror image) configuration at the assymmetric carbon atoms on the β-chain (the chain containing C₁₃ . . . C₁₄ etc.) to that of the respective nat and ent forms of the listed diastereoisomer; both of these diastereoisomers are claimed in this invention as well as their componenet enantiomers.

EXAMPLES 446-530

By the methods described hereinabove in Examples 319 and 320, the 1,9-dioxo-1-hydroxymethyl prostene derivative shown in Table 34 are prepared by the indicated method from the indicated vinyl iodide or vinyl tin compound and the indicated cyclopent-2-en-1-one.

In those cases where isomers are obtained at the C₁₅ or C₁₆ positions, only the C₁₅ or C₁₆ -normal isomers is listed in Table 34; it should be understood that the corresponding C₁₅ or C₁₆ -epi isomers are also formed and are part of this invention.

In those cases where the initial conjugate addition product contains a triphenylmethoxy blocking group, deblocking is conducted in acetic acid-tetrahydrofuran-water 4:2:1 at 50° C. for 5 hours.

EXAMPLES 531-553

By the methods described hereinabove in Examples 319 and 320, the 1,9-dioxo-1-hydroxymethyl prostene derivative shown in Table 35 are prepared by the indicated method from the indicated vinyl iodide or vinyl tin compound and the indicated cyclopent-2-en-1-one.

In those cases where two diastereoisomers are formed in the conjugate-addition, only one of the diastereoisomers is listed in Table 35. It should be understood that the other diastereoisomer is also formed which in its nat and ent forms has an opposite (mirror image) configuration at the assymmetri carbon atoms on the β-chain (the chain containing C₁₃ . . .

EXAMPLES 554-637

By the methods described hereinabove in Examples 319 and 320, the 1,9-dioxo-1-hydroxymethyl prostene derivative shown in Table 36 are prepared by the indicated method from the indicated vinyl iodide or vinyl tin compound and the indicated cyclopent-2-en-1-one.

In those cases where isomers are obtained at the C₁₅ or C₁₆ positions, only the C₁₅ or C₁₆ -normal isomers are listed in Table 36; it should be understood that the corresponding C₁₅ or C₁₆ -epi isomer is also formed and is part of this invention.

In those cases where the initial conjugate addition product contains a triphenylmethoxy blocking group, deblocking is conducted in acetic acid-tetrahydrofuran-water 4:2:1 at 50° C. for 5 hours.

EXAMPLES 747-769

By the methods described hereinabove in Examples 319 and 320, the 1,9-dioxo-1-hydroxymethyl prostene derivative shown in Table 39 are prepared by the indicated method from the indicated vinyl iodide or vinyl tin compound and the indicated cyclopent-2-en-1-one.

In those cases where two diastereosiomers are formed in the conjugate-addition, only one of the diastereoisomers is listed in Table 39. It should be understood that the other diastereoisomer is also formed which in its nat and ent forms has an opposite (mirror image) configuration at the assymmetric carbon atoms on the β-chain (the chain containing C₁₃ . . . C₁₄ etc.) to that of the respective nat and ent forms of the listed diastereoisomer; both of these diastereoisomers are claimed in this invention as well as their component enantiomers.

EXAMPLES 869-891

By the methods described hereinabove in Examples 773 and 774, the 1,9-dioxo-1-hydroxymethyl prostene derivatives shown in Table 41 are prepared by the indicated method from the indicated vinyl iodide or vinyl tin compound and the indicated cyclopent-2-en-1-one.

In those cases where two diastereoisomers are formed in the conjugate-addition, only one of the diastereoisomers is listed in Table 41. It should be understood that the other diastereoisomer is also formed which in its nat and ent forms has an opposite (mirror image) configuration at the assymmetric carbon atoms on the β-chain (the chain containing C₁₃ . . . C₁₄ etc.) to that of the respective nat and ent forms of the listed diastereoisomer; both of these diastereoisomers are claimed in this invention as well as their component enantiomers.

EXAMPLES 892-975

By the methods described hereinabove in Examples 773 and 774, the 1,9-dioxo-hydroxymethyl prostene derivatives shown in Table 42 are prepared by the indicated method from the indicated vinyl iodide or vinyl tin compound and the indicated cyclopent-2-en-1-one.

In those cases where isomers are obtained at the C₁₅ or C₁₆ positions, only the C₁₅ or C₁₆ -normal isomers are listed in Table 42; it should be understood that the corresponding C₁₅ or C₁₆ -epi isomers are also formed and are part of this invention.

In those cases where the initial conjugate-addition product contains a triphenylmethoxy blocking group, deblocking is conducted in acetic acid-tetrahydrofuran-water 4:2:1 at 50° C. for 5 hours.

EXAMPLES 976-998

By the methods described hereinabove in Examples 773 and 774, the 1,9-dioxo-1-hydroxymethyl prostene derivative shown in Table 43 are prepared by the indicated method from the indicated vinyl iodide or vinyl tin compound and the indicated cyclopent-2-en-1-one.

In those cases where two diastereoisomers are formed in the conjugate-addition, only one of the diastereoisomers is listed in Table 43. It should be understood that the other diastereoisomer is also formed which in its nat and ent forms has an opposite (mirror image) configuration at the assymmetri carbon atoms on the β-chain (the chain containing C₁₃ . . . C₁₄ (etc.) to that of the respective nat and ent forms of the listed diastereoisomer; both of these diastereoisomers are claimed in this invention as well as their component enantiomers.

EXAMPLES 994-1082

By the methods described hereinabove in Examples 773 and 774, the 1,9-dioxo-1-hydroxymethyl prostene derivative shown in Table 44 are prepared by the indicated method from the indicated vinyl iodide or vinyl tin compound and the indicated cyclopent-2-en-1-one.

In those cases where isomers are obtained at the C₁₅ or C₁₆ positions, only the C₁₅ or C₁₆ -normal isomers are listed in Table 44; it should be understood that the corresponding C₁₅ or C₁₆ -epi isomer is also formed and is part of this invention.

In those cases where the initial conjugate-addition product contains a triphenylmethoxy blocking group, deblocking is conducted in acetic acid-tetrahydrofuran-water 4:2:1 at 50° C. for 5 hours.

EXAMPLES 1083-1105

By the methods described hereinabove in Examples 773 and 774, the 1,9-dioxo-1-hydroxymethyl prostene derivative shown in Table 45 are prepared by the indicated method from the indicated vinyl iodide or vinyl tin compound and the indicated cyclopent-2-en-1-one.

In those cases where two diastereoiosmers are formed in the conjugate-addition, only one of the diastereoisomers is listed in Table 45. It should be understood that the other diastereoiosmer is also formed which in its nat and ent forms has an opposite (mirror image) configuration at the assymmetric carbon atoms on the β-chain (the chain containing C₁₃ . . . C₁₄ etc.) to that of the respective nat and ent forms of the listed diastereoisomer; both of these diastereoisomers are claimed in this invention as well as their component enantiomers.

EXAMPLES 1106-1189

By the methods described hereinabove in Examples 773 and 774, the 1,9-dioxo-1-hydroxymethylprostene derivatives shown in Table 46 are prepared by the indicated method from the indicated vinyl iodide or vinyl tin compound and the indicated cyclopent-2-en-1-one.

In those cases where isomers are obtained at the C₁₅ or C₁₆ positions, only the C₁₅ or C₁₆ -normal isomers are listed in Table 46; it should be understood that the corresponding C₁₅ or C₁₆ -epi isomers are also formed and are part of this invention.

In those cases where the initial conjugate-addition product contains a triphenylmethoxy blocking group, deblocking is conducted in acetic acid-tetrahydrofuran-water 4:2:1 at 50° C. for 5 hours.

EXAMPLES 1190-1212

By the methods described hereinabove in Examples 773 and 774, the 1,9-dioxo-1-hydroxymethyl prostene derivative shown in Table 47 are prepared by the indicated method from the indicated vinyl iodide or vinyl tin compound and the indicated cyclopent-2-en-1-one.

In those cases where two diastereoisomers are formed in the conjugate-addition, only one of the diastereoisomers is listed in Table 47. It should be understood that the other diastereoisomer is also formed which in its nat and ent forms has an opposite (mirror image) configuration at the assymmetricarbon atoms on the β-chain (the chain containing C₁₃. . . C₁₄ etc.) to that of the respective nat and ent forms of the listed diastereoisomer; both of these diastereoisomers are claimed in this invention as well as their component enantiomers.
